Abstract
Objective
This study aimed at examining the psychometric properties of Persian version of Multidimensional Health Locus of Control scale, form C (MHLC-C) among Iranian type 2 diabetes.
Method
This cross sectional study was conducted on 557 type 2 diabetes in eastern city of Iran in 2022. Participants were selected by proportional stratified sampling. The validity of MHLC-C was tested by face validity, content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA).Reliability of MHLC-C was assessed by McDonald omega coefficient, Cronbach's alpha coefficient, and Intraclass Correlation Coefficient.
Results
Based on the results of EFA, 4 factors with eigenvalues greater than 1 were extracted, which explained 61.66% of the variance. In EFA, a question was removed. In CFA, the factor loading of all questions was more than 0.4 and the indexes of the goodness-of-fit were acceptable (for example: X2/df = 4.457, RMSEA: 0.079, CFI = 0.904, and PGFI = 0.663). McDonald omega coefficient and Cronbach's alpha coefficient of MHLC-C were 0.869 and 0.866. The Intraclass Correlation Coefficient of MHLC-C was 0.817. Finally, the MHLC-C with 17 questions and 4 factors of chance (6 items), internal (5 items), other powerful people (3 items), and doctors (3 items) was approved.
Conclusions
The Persian version of the MHLC-C questionnaire, with 17 questions and four factors, is a valid and reliable scale for Iranian type 2 diabetes to assess their health locus of control status.
